Testcase from godbolt:
```
#include <ranges>
struct I {
int x;
using difference_type = std::ptrdiff_t;
using value_type = int;
constexpr I& operator++() { return *this; }
constexpr value_type operator*() const { return {}; }
constexpr I operator++(int) { return *this; }
constexpr bool operator==(const I&) const = default;
};
int main() {
constexpr std::ranges::subrange s = {I{}, I{4}};
auto split = s | std::views::lazy_split(0);
constexpr decltype(split.begin()) it;
}
```
Confirmed.
